Crosby was let go by the Dodgers on Wednesday.

EDGE Analysis

Crosby hooked on with the Dodgers in December but never received the opportunity to pitch in a game for the organization. The 31-year-old played independent ball last season and last pitched in the majors in 2012, when he made three starts for Detroit.

Crosby has signed with the Red Sox, Matt Eddy of Baseball America reports. Crosby has spent most of the past seven years in the Tigers' minor league program, and has struggled with injuries throughout his career. Even if he can stay healthy with Boston, he will likely spend the majority of the 2015 season in the minors, limiting any fantasy value.

Crosby was released by the Tigers on Monday, Chris Iott of MLive.com reports. In order to open up a 40-man roster spot, the Tigers have opted to jettison the 25-year-old left-hander. The move is warranted, as Crosby posted an unsightly 5.71 ERA, 1.637 WHIP, and 12:13 K:BB in 17.1 innings (11 outings) at Triple-A Toledo this season.

Casey Crosby (elbow) will throw a live batting practice session on Friday. Crosby started feeling elbow soreness a week ago, but he's progressing and could be cleared for game action soon. The southpaw is competing for a spot in the Tigers' bullpen.

Casey Crosby (elbow) threw a successful 25-pitch bullpen session on Sunday. Nursing some elbow discomfort and inflammation in his triceps, Crosby will have to throw at least one more bullpen session before being allow to face hitters and eventually getting into a Grapefruit League game.

Casey Crosby (elbow) has been shut down for a few days due to discomfort in his left elbow. The 25-year-old is expected to compete for a spot in the Tigers bullpen this spring. He'll be re-evaluated in a couple of days before determining a course of action.

Casey Crosby will compete for a job in the Tigers' bullpen during spring training. All 93 of Crosby's appearances between the minors and majors have come as a starter, but the Tigers have decided to shift him to a relief role. It's a move that's probably overdue, as Crosby has a big arm but has struggled to throw strikes throughout his pro career. With Ian Krol and Phil Coke already locked into relief roles, Crosby will surely begin 2014 at Triple-A. In time, he could develop into a bullpen weapon.

Tigers general manager Dave Dombrowski said Monday that Casey Crosby will likely be shifted to the bullpen. It makes sense, as Crosby had an ugly 4.84 ERA and 61/40 K/BB ratio over 57 2/3 innings in Triple-A this season while missing time with a shoulder impingement. His control has been a major issue as a starter, but he could be more effective in smaller doses out of the pen.

Tigers prospect left-hander Casey Crosby was placed on the 7-day disabled list with Triple-A due to a left shoulder impingement. Crosby felt some soreness during his recent start and will now get some extended rest. The 24-year-old southpaw has really struggled this season, posting an ugly 5.30 ERA and 39/28 K/BB ratio in 37 1/3 innings through eight starts.
